Study on Urban Renewal and Micro-Space Optimization Strategies in Zhengzhou: A Perspective on Function Enhancement and Cultural Heritage

Urban renewal is a crucial strategy to address issues such as inefficient land use, aging infrastructure, and environmental pressures in the process of rapid urbanization. Zhengzhou, the capital of Henan Province in central China and a key economic hub in the Central Plains region, faces challenges including low land utilization, deteriorating community environments, and insufficient public spaces. Micro-space renewal, as a cost-effective urban renewal approach, can enhance urban vitality and optimize residents' living conditions. This study focuses on micro-space renewal practices in Zhengzhou, employing a mixed research approach, including case studies, GIS spatial analysis, and surveys to assess micro-space utilization and gather stakeholders' input. The research combines cultural preservation with functional optimization, proposing strategies that integrate green design and digital technology. The findings demonstrate that optimized micro-space renewal can significantly improve public space quality, residents' well-being, and overall urban vitality, offering valuable insights for urban renewal in other medium-sized cities.
